贴片发光二极管的温度注意事项
信息来源于：互联网 发布于：2022-09-16
贴片发光二极管已逐步普遍应用人们日常生活当中，如手机、电脑、移动电源等，但对于产品制造者来说如何能更好的制造出良好的产品就可有学问了。
贴片发光二极管除了基本的使用注意事项外，还有个事项很容易给操作人员忽略掉。要注意温度的升高会使贴片发光二极管内阻变小当外界环境温度升高后，贴片发光二极管光源内阻会减小，若使用稳压电源供电会造成贴片发光二极管工作电流升高，当超过其额定工作电流后，会影响贴片发光二极管产品的使用寿命，严重的将使LED光源“烧坏”，因此最好选用恒流源供电，以保证LED的工作电流不受外界温度的影响。LED温度也是影响LED寿命的最重要的因素。请大家引起重视。
